Beyonce's mother Tina Knowles files for divorce

HOUSTON — Beyonce's mother, Tina Knowles, has filed for divorce from the pop diva's father and manager, Mathew Knowles.

Tina Knowles began legal proceedings Nov. 11, according to documents filed with the Harris County Court Clerk. She launched the House of Dereon clothing line with Beyonce in 2006.

"The decision to end our marriage is an amicable one. We remain friends, parents, and business partners," the couple said in a statement provided to The Associated Press on Friday. "If anyone is expecting an ugly messy fight, they will be sadly disappointed. We ask for your respect of our privacy as we handle this matter."

The divorce filing came about a month after Mathew Knowles was named in a paternity suit. Los Angeles resident Alexsandra Wright claims in the lawsuit that he is the father of her unborn child.

Tina and Mathew Knowles wed in 1980. In addition to 27-year-old Beyonce, they have another daughter, 23-year-old singer Solange.
